Question

1.Two ramps of different lengths are used
to lift furniture into the same truck.
Which ramp requires less force?

2.Explain the difference between a
mechanism and a simple machine.

3.A metre stick is used as a lever. If the
input force is applied at 0 cm and the
the output force is exerted at 100 cm, what is
the ideal mechanical advantage if the
fulcrum is at 75 cm?

4.As the mechanical advantage of a simple
machine is increased, how does the
distance of the input force compare to the
distance of the output force?

Answer 1

Answer:

1.Two ramps of different lengths are used

to lift furniture into the same truck.

Which ramp requires less force?

---> false

2.Explain the difference between a

mechanism and a simple machine.

---> true

3.A metre stick is used as a lever. If the

input force is applied at 0 cm and the

the output force is exerted at 100 cm, what is

the ideal mechanical advantage if the

fulcrum is at 75 cm

--->> yes

4.As the mechanical advantage of a simple

machine is increased, how does the

distance of the input force compare to the

distance of the output force

---> false
